  By the way, in the structure of patent document 1, the spring which has the above-mentioned elastic contact piece is being fixed to the inside of a movement block by press injection or insert molding. When the elastic contact piece is fixed in this manner, the dimensional tolerance that allows the elastic contact piece to sandwich the overlapped bus bar is the tip of the pair of flexure pieces protruding below the fixed elastic contact piece. Is limited to a predetermined dimension inside. On the other hand, if the dimensional tolerance that allows the elastic contact pieces to sandwich the overlapped bus bar can be made larger than this predetermined dimension, problems when inserting the overlapped bus bar into the elastic member can be prevented. It is desirable because it can.

  The present invention has been completed based on the above circumstances, and is a bus bar connection capable of increasing the tolerance of dimensions allowing insertion of a superimposed bus bar while ensuring the contact pressure between the bus bars. The purpose is to provide ingredients.

  According to the present invention, a pair of flexures of an elastic member accommodated in a synthetic resin housing is formed by overlapping a plurality of bus bars for connection in one and the other devices each having a connection bus bar. In the bus bar connector that is sandwiched between and connected to each other, the housing includes a housing chamber that houses the elastic member, and the housing chamber has an opening that allows the overlapping bus bar to be inserted into the housing chamber. The elastic member accommodated in the accommodation chamber is configured to be able to change the position and posture in the accommodation chamber within a predetermined range, and the pair of flexure pieces includes the elastic member in the accommodation chamber. An abutting portion that abuts on the overlapping bus bar inserted into the opening in the predetermined range of the position and posture of the elastic member that can be changed is provided. The overlapping bus bar that is in contact with the contact portion is characterized in that the elastic member is moved in the accommodating chamber so that the overlapping bus bar is positioned between the pair of flexure pieces. .

According to this configuration, since the elastic member accommodated in the accommodating chamber is configured to be able to change the position and posture in the accommodating chamber within a predetermined range, the tolerance of the dimension into which the overlapping bus bar can be inserted is set to the elastic member. Can be set larger than the dimension between the pair of flexure pieces in the case where is fixed to the housing.
In addition, even if the position and posture of the elastic member can be changed as described above, the pair of flexure pieces are provided in the opening portion within a predetermined range of the position and posture of the elastic member that can be changed in the storage chamber. An abutting portion that abuts against the inserted overlapping bus bar is provided, and the overlapping bus bar that abuts against the abutting portion accommodates the elastic member so that the overlapping bus bar is positioned between the pair of flexure pieces. Therefore, the overlapping bus bars can be sandwiched by the elastic force between the pair of flexure pieces, and a connection with a predetermined contact pressure can be ensured between the connecting bus bars in the overlapping bus bar.
Therefore, with respect to the bus bar connector, it is possible to increase the tolerance of the dimension in which the bus bar in an overlapped state can be inserted while ensuring the contact pressure between the bus bars.

It is more preferable to have the following configuration in addition to the above configuration.
A guide portion that guides the overlapping bus bar into the accommodation chamber is formed in the opening.
In this way, the overlapping bus bar can be guided into the accommodating chamber in the range where the guide portion is formed. Therefore, it is possible to further increase the tolerance of the dimension in which the overlapping bus bar can be inserted.

The housing includes a main body portion that is open at one end of the housing chamber and a cover portion that is attached to the open portion of the main body portion, and the opening portion is provided in the cover portion. .

In the configuration in which the elastic members are respectively stored in the plurality of storage chambers, a plurality of overlapping bus bars sandwiched between the elastic members are also provided. Therefore, a dimensional error may occur between the plurality of overlapping bus bars. According to this configuration, when a dimensional error between a plurality of overlapping bus bars is likely to occur in this way, the tolerance of the dimension in which the overlapping bus bar can be inserted can be increased, thereby preventing a problem due to the dimensional error. It becomes possible to do.

A plurality of the storage chambers are provided side by side in the housing, a partition wall is provided between the plurality of storage chambers in the main body portion, and the cover portion projects so as to be continuous with the partition wall. The partition convex part to be provided is provided, and the side surface of the partition convex part serves as a locking part in which the tip ends of the pair of flexure pieces are locked.
If it does in this way, it will become possible to lock a bending piece to a locking part using composition of a cover provided in order to make accommodation of an elastic member easy.

<Embodiment>
An embodiment of the present invention will be described with reference to the drawings of FIGS.
The bus bar connector 10 of the present embodiment is for connection by generating contact pressure between the connection bus bars 41 and 44 extending from one device 40 and the other device 42 arranged in a vehicle such as an automobile. The bus bars 41 and 44 are connected. In the following, the vertical direction and the horizontal direction will be described with reference to FIG. 1, with the front side of the page of FIG. 1 as the front and the back side of the page as the back.

(machine)
As shown in FIG. 2, one device 40 houses a device main body (not shown) in a box-shaped device case 40A. The device case 40A is made of metal and is fixed to the body of an automobile, for example.
The device 40 includes a plurality of (eight in FIG. 2) plate-like connection bus bars 41 protruding upward from an internal device body through an insertion hole (not shown) provided on the upper surface of the device case 40A. Are arranged side by side at equal intervals in the left-right direction (thickness direction of the connecting bus bar 41).

The other device 42 is arranged in a different location from the one device 40 in the automobile, and a bus bar 43 extends in the left-right direction from the other device 42.
The end of the bus bar 43 is bent in an L shape, and the end of the bus bar 43 is a plate-like connection bus bar 44 extending in the vertical direction. It is also possible to connect the other device 42 to the connecting bus bar 44 via an electric wire. In this case, the connecting bus bar is attached to a terminal fitting attached to the end of the electric wire by a known connecting means such as crimping. 44 may be formed.

  The connection bus bar 41 of the one device 40 and the connection bus bar 44 of the other device 42 overlap each other by being in contact with each other or forming a slight gap, thereby overlapping each other. , 44 are overlaid, and an overlapping bus bar 45 is configured.

(Bus bar connector)
The bus bar connector 10 includes a plurality of elastic members 11 and a housing 17 in which the elastic members 11 are accommodated.
The elastic member 11 is made of, for example, a metal made of stainless steel or iron, and is formed by bending a band-shaped metal plate material into a substantially U shape. More specifically, as shown in FIG. , And a connecting portion 16 connected in a circular arc shape to the base ends of the pair of bending pieces 12 and 12.

  The pair of bending pieces 12, 12 are divided into inner inclined portions 13, 13 inclined so as to reduce the dimension between the pair of bending pieces 12, 12 from the base end portion on the connecting portion 16 side, and inner inclined portions 13, 13. There are divergent curved portions 15 and 15 that are curved in an arc shape so as to spread outward (in a direction away from each other) toward the distal end portions of the continuous bending pieces 12 and 12, and the inner inclined portions 13 and 13 and the divergent curved portions 15 and 15 are provided. The boundary portions are formed as narrow portions 14 and 14 where the two bent pieces 12 and 12 are closest to each other.

Of the pair of flexure pieces 12, 12, the dimension between the narrow portions 14, 14 (the dimension between the inner surfaces of the narrow portions before insertion of the overlapping bus bar 45) is such that the two connecting bus bars 41, 44 are spaced apart. It is smaller than the thickness dimension of the overlapping bus bar 45 in a closely contacted state. As a result, when the overlapping bus bar 45 is inserted between the pair of flexible pieces 12 and 12, the pair of flexible pieces 12 and 12 are deformed outward and the two connecting bus bars are elastically restored. A contact pressure is generated between 41 and 44.
The inner surface side (lower surface side) of the divergent curved portions 15 and 15 are contact portions 15A and 15A with which the tip 45A of the overlapping bus bar 45 contacts.

As shown in FIG. 5, the housing 17 includes a main body portion 18 provided with receiving recesses 20 for storing the elastic member 11 and a cover portion 25 that covers the lower portion of the main body portion 18.
The main body portion 18 includes a box-shaped accommodation portion 19 that accommodates the plurality of elastic members 11, and a flange portion 22 that projects outward from the lower end of the accommodation portion 19 in a bowl shape.

The accommodating portion 19 is provided with a plurality of accommodating recesses 20 in which the elastic member 11 is accommodated side by side, and the accommodating recesses 20 are partitioned by a partition wall 20A.
As shown in FIG. 3, a lock protrusion 21 is formed on the side surface of the accommodating portion 19. The lock protrusion 21 protrudes in a stepped shape, and has a shape in which the protrusion dimension is reduced in an inclined manner toward the cover portion 25 side.

  As shown in FIG. 5, the flange portion 22 has a circular attachment hole 23 formed therethrough. A cylindrical collar (not shown) through which the shaft portion of the bolt BT is inserted is fitted into the mounting hole 23, and the bolt BT is provided in the mounted member 24 as shown in FIG. 2. The housing 17 is attached to the attached member 24 by bolting the bolt hole 24A having a thread groove. The housing 17 may be covered with a metal shield shell that generates a shield function, and the shield shell may be attached to the member 24 to be attached.

  As shown in FIG. 5, the cover portion 25 is attached to the lower end side (opening side) of the housing portion 19 and forms the bottom wall of the plurality of housing chambers 26 in which the elastic members 11 are housed. And a partition convex portion 29 that protrudes above the plate-like portion 27 and abuts against the lower end of the partition wall 20A.

The plate-like portion 27 is covered with the accommodation recess 20 to constitute the accommodation chamber 26 that can accommodate the elastic member 11, and the plate-like portion 27 forms each bottom wall of the accommodation chamber 26.
An opening 28 through which the overlapping bus bar 45 can be inserted is formed through the plate-like portion 27.

As shown in FIG. 6, the opening 28 is formed through the plate-like portion 27 and has a guide portion 28 </ b> A that guides the overlapping bus bar 45 into the accommodation chamber 26.
The guide portion 28A is an inclined surface that increases the opening diameter in an inclined manner from the opening end 28B (slightly below) of the upper end of the opening portion 28 (the end portion on the housing chamber 26 side) toward the lower side (outer surface). When the leading end 45A of the overlapping bus bar 45 comes into contact with the guide portion 28A, the leading end 45A of the overlapping bus bar 45 moves to the opening end 28B while being in sliding contact with the guide portion 28A. Note that the direction of the overlapping bus bar 45 (posture extending in the vertical direction) is almost the same because the connecting bus bars 41 and 44 are firmly held by the devices 40 and 42.

As shown in FIG. 8, the partition convex portion 29 protrudes in a mountain shape from the upper surface of the plate-like portion 27, and the upper end thereof is an abutting surface 29 </ b> A that abuts against the lower end of the partition wall 20 </ b> A. The corners are tapered.
The side surface of the partition convex portion 29 is a locking portion 29B to which the distal end portions (end surfaces) of the bending pieces 12 and 12 are locked when the elastic member 11 moves to the left or right or the posture of the elastic member 11 is inclined. It is said that. The locking portion 29B protrudes inward from the surface of the partition wall 20A, and the leading end portions of the bending pieces 12 and 12 are locked to the locking portion 29B, whereby the elastic member 11 in the accommodation chamber 26 is predetermined. The above movement and posture change are regulated.
The partition convex portions 29 are connected to the lower end of the partition wall 20A, whereby the side walls of the respective storage chambers 26 are formed.

The accommodating chamber 26 has a substantially rectangular cross section, and has a clearance that allows the position and posture of the elastic member 11 to be changed within a predetermined range between the elastic member 11 and the elastic member 11 when the elastic member 11 is accommodated. ing. Thus, the elastic member 11 is allowed to move in the left-right direction within the clearance within the accommodation chamber 26, and the posture of the elastic member 11 is also allowed to be inclined according to the clearance. (FIGS. 8 to 11).
As shown in FIG. 3, a frame-shaped lock receiving portion 30 that is engaged with the lock protrusion 21 of the main body portion 18 is formed on the side surface of the cover portion 25. The protrusion 21 is disposed and locked in the lock receiving portion 30 so that the detachment of the cover portion 25 is restricted.

Here, as shown in FIG. 13, the elastic member 11 and the storage chamber 26 are arranged in the left-right direction between the lower ends (tips) of the pair of bending pieces 12 and 12 when the elastic member 11 is tilted to the maximum in the storage chamber 26. A dimension A cos θ (that is, a dimension obtained by projecting the dimension A between the lower ends of the pair of flexible pieces 12, 12 of the elastic member 11 inclined at an angle θ with respect to the left-right direction on the surface in the left-right direction) The dimension (W / 2 + S /) between the engaging portion 29BA (29B) and the other opening end 28BB (28B) on the side farther from the one engaging portion 29BA of the opening portion 28 (the back end portion thereof). 2) It is larger.
That is, it is set in a range where A cos θ> (W + S) / 2.
Here, “W” in the above expression is a dimension between the left and right partitioning convex portions 29 (the locking portions 29B). FIG. 13 shows the relationship between the dimension between the one locking portion 29BA and the other opening end 28BB and the dimension of the elastic member 11, but the other locking portion 29BB (29B) The relationship between the dimension between the opening end 28BA and the dimension of the elastic member 11 is set similarly.

  As shown in FIG. 14, the “lower end of the pair of bending pieces 12, 12” is used when the fan-shaped angle φ (center angle) with the diverging curved portions 15, 15 as an arc is 90 degrees or more. The lower end of the circle including the arcs of the divergent curved portions 15 and 15 is, as shown in FIG. 15, the fan-shaped angle φ (center angle) having the arc of the divergent curved portions 15 and 15 is less than 90 degrees. The lower end of the pair of flexure pieces 12, 12 is not the lower end of the circle.

Next, assembly of the bus bar connector 10 to the overlapping bus bar 45 will be described.
The bus bar connector 10 is lowered and the opening 28 side of the bus bar connector 10 is overlapped and brought closer to the bus bar 45 (see FIG. 2). At this time, the position of the connecting bus bars 41, 44 constituting the overlapping bus bar 45 in the left-right direction is outside the region in the upper end opening 28B as shown in FIGS. However, if the connection bus bars 41 and 44 are inside the guide portion 28A, the positions of the connection bus bars 41 and 44 are guided inside the opening end 28B by abutting against the inclined surface of the guide portion 28A.

  Then, the bus bar connector 10 is further lowered from there. At this time, when the position of the overlapping bus bar 45 is not at the center between the diverging curved portions 15 and 15 of the flexure pieces 12 and 12, as shown in FIGS. The connecting bus bars 41 and 44 constituting the overlapping bus bar 45 abut on the 15 abutting portions 15A.

  The flexure pieces 12, 12 that have received force from the connection bus bars 41, 44 are flexibly deformed, and the accommodating chamber 26 of the elastic member 11 is positioned so that the connection bus bars 41, 44 are positioned between the pair of flexure pieces 12, 12. The position and orientation inside are changed to, for example, the position of the elastic member 11 </ b> A indicated by the two-dot chain line in FIGS. 8 to 11. When the bus bar connector 10 is further lowered, the overlapping bus bar 45 enters inside while elastically deforming between the pair of flexible pieces 12, 12, and the overlapping bus bar 45 is between the pair of flexible pieces 12, 12. (FIG. 12). At this time, a predetermined contact pressure is generated between the connecting bus bars 41 and 44 sandwiched by the elastic restoring force of the elastic member 11.
